3 inch male spigot
Review by
This was just what I needed to repair my black water tank. The original connection had been repaired once before but was now cracked and leaking again. I cut it off flush at the tank and glued this fitting into the tank using black ABS glue. Although the tank is not made of ABS plastic , the glue worked fine. I then was able to reconnect my waste pipe using standard 3" fittings. So far, no leaks, no problems.

Bought this fitting along with several others because I wasn't sure which one I would need. Looks like this one was designed to glue onto a holding tank made out of ABS plastic in order to give a raised "spigot" that is the same OD as a 3" ABS pipe. This would allow you to glue an ABS fitting such as an elbow or coupler to the fitting in order to connect plumbing.
